IMPROVEMENT IN SPRING-GUNS.

Specification forming part of Letters Patent No. 220,325, dated October7, 1879; application filed July 22, 1879.

tion thereof.

My invention relates to an apparatus for throwlngmisslles, projectiles,or arrows, which V I call the telepult and it consists of a gun orweapon having a barrel suitably connected with a stock and having a slotin its lower part.

A driving-block for the arrow or projectile moves in the barrel, and hasa stem projecting down through the slot, so as to have the firingelastic straps attached to it. These straps are contained in a chamberbeneath the barrel, and have one end secured at the front, so that theirtension may be regulated. A bar extends across this chamber, and,projecting out through slots at the sides, has buttons attached to itsouter ends. The stem of the driver and the ends of the elasticfiring-straps are connected with the cross-bar, and by drawing thebuttons back until the bar engages with the trigger or detent, the arrowmay be placed in the barrel, and the weapon is ready for firing. This isaccomplished by pulling the trig ger and releasing the bar.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 :is a perspective view of my gun. Fig. 2 is alongitudinal section. Fig. 3 is a transverse section.

The barrel A is ahollow cylindrical tube, made of any suitable material,having at its bottom a longitudinal incision or slot, made tfor thepurpose of admitting a metal shank, B, and head 0 of the discharger,hereinafter described, by the forward motion of which any missile placedproperly within said barrel is eflectively delivered in a straight line.

The barrel is held in its place by a fastening, D, at its base or breechend, and by a clamp, E, at its outer end or near to that end, ashereinafter described.

The three parts of metal are the combined loader and discharger F, thecombined clamp and box IE, and the combined automatic powercatch andlev.er-trigger.

The combined loader and discharger c011- sists of a straight bar, F, ofsteel or other metal,'capped at both ends by knobs of metal H, andbearing in the center of said bar a shank, B, of metal, extending upwardwithin the incision of the barrel into its cavity, and there terminatingin a round ball or head, 0, the purpose of which is, by its motion fromthe back part of said cavity in the barrel toward the front part of thesame, to expel the missile that may be placed within said barrel.

The knobs before mentioned are for the purpose of drawing the combinedloader and discharger back toward the breech of the barrel, for thepurpose hereinafter described.

' The combined clamp-box E passes around the end of the barrel and overthe end of the stock G, and when in position holds securely the ends ofthe stock and barrel, at the same time clamps the rebounding pad J, towhich the elastic straps I are secured, between the grooved or serratedfaces a a of the stock and barrel, thus holding said pad securely inposition, and the expansive force of the elastic pad tending to forcethe barrel A and stock G apart, bears them against the fastening Esufficiently hard to prevent it from slipping off.

The combined automatic catch and levertrigger K is so arranged that aspring, L, rises immediately after the passage backward ot' the bar ofthe loader, and in this manner secures the bar F, which is thus retaineduntil it is discharged at the will of the user of the weapon by themovement of the trigger. trigger K is hinged to a link, M, whichconnects it with the spring L, and in such a manner that the rear partthe trigger acts as a lever, pressing upon the lower partof the stock,when pulled, so as to act upon the link and spring-catch.

The three parts of india-rnbber are the two propelling straps or bands Iand the rebound ing pad J.

The propelling straps or bands are of india-rubber, and are fastened attheir ends nearest to the breech of the gun to the before-mentioned barF of the combined loader and discharger, while at their other end theyare secured in the rebounding pad by the clamp-box in such amanner thatthe drawing The back of the combined loader and discharger produces atension of the bands or straps, and the power so obtained is secured bythe bar F passing back of the automatic catch K, and so remains readyfor delivery in a direct line for the propulsion ot the arrow-bolt orbullet placed within the barrel of the weapon for use as a missile.

The other part of india-rubber is the re bounding pad and combinedband-fastener J. Its uses are three: First, to arrest the bar F and head0 without injury and with the least possible noise when its missile hasbeen ex pelled; secondly, to hold securely the outer fixed end of theindia-rubber straps, both while in place for action, and also whendisconnected in part by the removal of the combined clampbox, as may bedone for examination or adj nstment when either may be necessary;thirdly, by its elasticity to aid in keeping the clampbox in its properplace; still further, the rebounding pad, being movable, may be changedeither to a horizontal or a vertical position between the stock andbarrel, and by this the tension of the straps or hands attachedincreased or diminished, as may be desired.

By this construction I am enabled to apply the force of the elasticpropelling straps or bands in a line with the direct motion of theprojectile, while the barrel has no side openin gs,

and the elastic straps are concealed and protected. They are secured inplace and adjusted by the rebounding pad and clamp, which also receivesand checks the forward impulse of the driver and bar. The weapon may beproperly sighted and is very accurate.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The barrel A, with the head or driver 0, connected by the shank Bwith the bar F, in combination with the elastic straps I, inclosedwithin tl1e stock below the barrel, said straps having one end securedto the bar, while the other is retained and adjusted by the pad J,substantially as herein described.

2. The barrel A, secured to the stock G by the clamps D and E, incombination with the elastic pad J, whereby the clamp E is held inplace, the driver 0 and bar F are checked in their forward movement. andthe tensions of the straps I are adapted to be adjusted, substantiallyas herein described.

In witness whereof I have hereunto set my hand.

RICHARD WYLIE.
